It looks like Heidi Klum is a single woman once again as reports have surfaced that the supermodel has split from her boyfriend Martin Kirsten. The 40-year-old called it quits with her bodyguard beau after more than a year of dating.

According to Us Weekly, a source confirmed the break up. The insider said, "He is no longer working with her or her family."

The gorgeous blonde first confirmed her relationship with Kirsten during an interview on Katie Couric's talk show back in September 2012, shortly after filing for divorce from husband of nearly seven years, Seal.

At the time Klum explained the new romance. She said, "He's been with our family for the last four years . . . He's cared for our entire family, mostly for our four children, helped us tremendously," adding, "I trust him with my children's life. He's a great man . . . and we just got to know each other from a completely different side."

Coincidently although she was in a serious relationship with her Martin Kristen, Heidi Klum's divorce from Seal, 50, has yet to be finalized.

Despite the end of their marriage the two remain on very good terms. The former couple was even spotted sharing a friendly kiss hello back in October while celebrating their daughter Lou's 4th birthday together.

The gorgeous German decided to have a positive outlook following her split from Seal and told Couric in September 2012 that she and Seal had both moved on.

She admitted, "I do want to date again," adding, "I'm turning 40. I don't even know where it's going to go."
